I'm going to take the risk of jinxing myself here.

If I wipe out in my tri next week, we'll know the real cause, won't we?

OK.

I have not fallen off my bike since high school. I had two falls, both riding whatever cheap, skinny tired bike I had back then. (It was the 70s) One was a wipe out on ice on the way to school. I arrived all scraped up under my jeans. I guess it was probably early spring, with patches of ice still on the streets. I took a corner and .... down! The other was riding to work at a small bookstore, where I'd be the only employee in that day. Again, skinny tired bike. Rutted dirt path. Tire went one way, I went the other. Landed on the left side of my face. Nobody wore helmets back then, come to think of it. I was a mess, and I went to work anyway, tried to clean myself up as best I could. I can't remember how I got home. The bike was OK. Maybe I even rode home. I ended up needing derm treatment for infections on my face from the dirt. I've got three small scars to prove it.

I've had a couple of near misses with the clip ins, but have always gotten out in time.

Sooo...how to vote? That's one sideways slide and one over the bars.
